Table 1 Chemical composition of as-cast AZ80 magnesium alloy, wt-%
Figure 6 shows the SEM micrographs of AZ80 alloy aged at 200   for various periods, from which the coarse white  β-Mg 17 Al 12  particle can be still observed in the specimens after solution treatment (395  , 12 h, water-cooling)
Table 2 listed the average values of Brinell hardness (HB), tensile strength ( R m ), yield strength ( R P0.2 ) and elongation ( A 5 ) for all of the specimens tested in the study
